## Overview

This is a small Flask dataset-summary viewer. A visitor can open the landing page or request the data-loading page; that route asks the data helper to read a CSV and assemble dimensions, column metadata, missing-value counts, and a preview, then renders the result or an error in the shared template. The tree includes styling, but its use is not established by the sampled source. Despite the dataset filename, no placement-prediction workflow is evidenced.

Main entry points: [`project/app.py`](https://github.com/dev2490/pythonproject2/blob/main/project/app.py) (Flask routes), [`project/load_data.py`](https://github.com/dev2490/pythonproject2/blob/main/project/load_data.py) (Summary loader), [`project/templates/index.html`](https://github.com/dev2490/pythonproject2/blob/main/project/templates/index.html) (Page template), [`project/placement_predict_50k Dataset.csv`](https://github.com/dev2490/pythonproject2/blob/main/project/placement_predict_50k%20Dataset.csv) (Placement dataset)

## Components

### Web interface

- [Flask routes](https://github.com/dev2490/pythonproject2/blob/main/project/app.py): `project/app.py`
- [Page template](https://github.com/dev2490/pythonproject2/blob/main/project/templates/index.html): `project/templates/index.html`

### Data summary
